What is it? Satnavs are great, but not exactly practical for use on a bike – the screens are too detailed to look at quickly, and you can’t hear the instructions over the sound of the lorry running over your legs. Hammerhead One, though, promises to be a much safer option. When’s it due? Buy it now. Why are we excited? Its simplicity makes it both safe and practical. Lights on either the left or right prong come on as you approach the appropriate turning, and the device flashes red when it spots obstacles in the road. It’ll help keep your eyes on the road and your bike on the right route.
